How to Choose the Right Mask

A well-fitting mask can make or break a dive. When it fits, you feel relaxed, confident, and connected to the underwater world. When it doesn’t, you’re stuck clearing leaks, adjusting straps, and missing the magic around you. Choosing the right mask is one of the most important gear decisions you’ll make — and it’s easier than you think.

Single Lens - Low Profile Mask

Start With the Seal

A mask should seal to your face without the strap. Place the mask gently on your face, inhale slightly through your nose, and let go. If it stays in place, you’ve found a good seal.

Consider Your Face Shape

Different masks fit different structures: narrow faces, wider faces, high or low nose bridges, and prominent cheekbones. There’s no “one size fits all.” Try several.

Single Lens vs. Dual Lens

Scuba quality lenses are tempered glass. Single lens masks offer a wide, open view and are great for photographers. Dual lens masks often have lower volume, are usually easier to clear, and often better for prescription lenses. Some masks have a side lens to allow for a wider view. Choose based on comfort and purpose.

Double Lens Masks

Specialty Lens

Lenses come in assorted colors. Colored lens offset the color changes that occur due to depth, work with fluorescence lights, or reduce glare. While these lenses aid the wearer, they can make it difficult to see the wearer's eyes. Some double lens masks have interchangeable lenses with optic readers. Divers may also choose to have a prescription placed in their mask.

Skirt Material Matters

Look for soft silicone (not PVC), flexible edges, and a comfortable nose pocket. Avoid stiff skirts — they cause leaks and pressure points. Choose a solid or a clear skirt according to your preference. Note that clear skirts tend to turn yellow as they age.

Straps and Buckles

A good strap system should adjust easily, sit comfortably, and stay secure without overtightening. Straps can be made out of elastic, neoprene, velcro, or silicone. Overtightening can make it more difficult to clear or equalize the mask. Also, it can pucker the skin causing a steady stream of water to trickle and fill up your mask. Remember: the strap keeps the mask in place — the seal keeps water out.

Try It With a Snorkel & Regulator

Some masks feel great alone but uncomfortable once a snorkel is attached or you use a regulator. Test the full setup. Inserting the mouthpiece may change the shape of your mouth creating lines and crevices that can cause your mask to leak.

Purge Valves

A purge valve scuba mask is a dive mask that includes a small one‑way valve located at the bottom of the nose pocket. The valve lets you easily expel water from inside the mask by gently exhaling through your nose. The valve opens to release air and water but prevents water from coming back in. The placement of the valve may make it harder to squeeze the nose pocket to equalize your ears. The purge valve can be a point of failure. Some divers complain about the valve rubbing their nose causing discomfort.

Full Face Masks

Full Face Masks (FFMs) are an option after you have mask clearing and replacement. FFM masks have the regulator built into the masks. The FFM Specialty teaches you how to clear the mask, equalize, and switch from a FFM to a regular mask and regulator in underwater emergencies.

The Right Mask Transforms Your Entire Dive

Your mask is your window to the underwater world. Choose comfort over aesthetics, fit over features, and trust your instincts. When your mask feels right, everything else becomes easier.
